Passat (B5) :: 2003 - Check Engine Light Coming On

I have about 75K on my 03 1.8t on started having the check engine light coming on in the last few months. The dealers diagnosis was that I wasn't tightening the gas cap enough but I don't believe that because I do at least 3-5 clicks when I close it. I'm a bit baffled. After the last time I filled up at the gas station, I noticed the cap was loose so I've ordered another cap thinking the last one has lost its ability to seal properly...

Passat (B5) :: 2003 1.8T - Check Engine Light On / Multiple Misfires

My daughter has a 2003 Passat Turbo. Two weeks ago it started to run like crap with a check engine light on. I pulled the codes and it said multiple misfires. My buddy owns his own shop and said bring it down. He pulled the plugs and the spark plug holes were filled with oil. He changed the valve cover gaskets and replaced the plugs. Still ran rough with low fuel pressure so he replace the fuel pump and injectors. Still runs rough, when he pulled the air intake off there was oil in it. Could this have happened do to the valve cover gasket? The codes still read misfires. He said the turbo was full of oil also. Could the turbo be bad causing it to run like crap? Can it be rebuilt? I really don't want to go to the dealer.

Passat (B5) :: 2003 - Check Engine Light Came On And Car Is Running Really Rough At Stops

I have an 03 Passat with about 70K miles on it. My daughter put rug in it this morning (about 7 gallons) and since then the check engine light came on and the car is running really rough at stops. While accelerating, it seems to be fine. It is also getting about 10 mpg less than normal. MIL codes: P0300, P0301, P0302, P0303, P0304, and P0171. He said the P03xx codes were related to misfirings on each cylinder. The P0171 is a bank 1 failure (?). What do those codes really mean and could they be related to bad gas? Sent her off in my TDI JSW so she's not out on the highway if the Passat decides it doesn't want to go anymore.

Passat - Volkswagen :: 2003 - Check Engine Light Is On / Code Is P0778

We have a 2003 VW Passat 1.8, front wheel drive. The check engine light is on. The code is p0778. When we start the car the gears light display lights up in red for all gears . We put the car in reverse, back out the garage and when we stop, we get a bump. And we shift to drive the car moves slowly with some hesitation.

Sometimes after the car runs for 10 minutes, then turned of for a few second then started up again, the problem goes away. Before this problem started, we would start the car in the mornings, and put in "R" , and only the reverse gear would light up. (which is the way it is suppose to work).

Passat (B5) :: Check Engine Light Came On After New Engine Installed

Okay, I bought this car used and the previous owner apparently didn't maintain it. So I spent the last couple months having a new (used) engine installed. All said it's been in the shop longer (by twice) than I've been driving it. On the way home from the mechanic the check engine light came on.

If I keep changing my oil every 2000 miles will it sludge again? Dealer recommended every 1500 to 2000 miles! I've spent 15k on this car so far, and driven it about 2k miles......

Passat (B5) :: 2001 V6 - Check Engine Light On?

I have had a check engine light on in my car for a while now. I am pretty sure that it deals with the disconnection of the vacuum servo that controls the intake manifold's flaps that designate which track the air takes through the manifold. It has been running fine like this for a while under the assumption that because the performance of the vehicle hasn't changed, there is no need for immediate repair.

Here is my new problem which I am trying to determine if it has to do with the above issue. Over the past few days my car has been giving me EPC and ASR lights along with switching to back-up power. I have been on expressways driving 80, i have been going around corners doing less than 20, and it has happened everywhere in between. Keep in mind that when it happens i slip my car into neutral, pull over, and reboot. After that everything is fine for a short while. I stopped at Auto Zone to get a diagnostic, and for some reason, which i did not feel like questioning due to the way the autozone employee was mentally equipped, they did not give me codes, but descriptions.

(1) Camshaft Positioning Sensor Fault A Bank 1
(2) Camshaft Positioning Sensor Fault A Bank 2
(3) PCM Processor Fault
(4) Running too lean on Bank 1
(5) Running too lean on bank 2.

These are the descriptions for the 5 fault codes. I am planning on stopping back today and getting the proper codes. But would like to get some opinions in the mean time. I've check fuses and relays pertaining to this issue and all have tested ok. Nothing is leaking from my engine and nothing is visibly damaged, except for the vacuum servo arm which is broken (see above paragraph). I feel like the issue is with the ECM (PCM, PCM, ECU, whatever).

Another interesting thing is that when i operate my car using the cruise control, there are no issues what so ever. Possibly an issue with the throttle or its many components?

Passat (B5) :: How To Reset Check Engine Light

After I finally got around to replacing my ABS pump I went to get my smog check done. Passed except I didn't drive enough miles to qualify.The SMOG tech told me to drive 150 miles and come back. I drive the 150 plus miles and within that time my check engine light comes on. I go to the shop and have it reset.

How many miles do I have to drive the car after a Check Engine Light reset in order to qualify for a Cali SMOG Check.

Passat (B6) :: Check Engine Light - Air Intake?

I have taken my car into service twice because of the check engine light being on. They fix it and say it has something to do with the intake. It is now on for a third time. Obviously they are not fixing the problem. BTW, I have done no modifications to my car.

Passat (B5) :: Check Engine Light Came On - How To Get Diagnostic

Ok, recently my check engine light came on and i read the code with a cheap-o scanner. It read an o2 sensor code (up stream) i then read it again with a scanner that advanced auto parts offers for use, and it read p 1138 i think. I looked the code up on line and it was a fuel lean bank 1 or something like that. All the info i found sugests a smoke test of the vacumm system. I fist did a visual check of the hoses and also a few burst of carb cleaner and listened for the idle to raise but got no results. I also changed the o2 sensor for good measure, is there anything else i can try before i shell out the cash for a full diagnostic.

Passat (B5) :: Check Engine Light Pop Up - IAT Sensor

I had a check engine light pop up and I went and got it checked out. Comes to be its a IAT sensor or bad connection with this sensor. I change the sensor and made sure the wires on it is all good. The question is, I still have the check engine light up, does the code need to be deleted? And what happens if the code gets deleted and problem is not fixed?

Passat (B5) :: Check Engine Light Came On Repeatedly - Gas Cap?

So I've just come back from the 5th time visiting the dealership for them to clear the "CHECK ENGINE" light off of my dash. Each time they've told me that it is my gas cap....so on the 4th time I bought a brand new gas cap. This time the car drove for 478kms...then the light came on again. I know they are just gonna say EVAP (gas cap issue).

What is the next step? What else could be tripping this fault?

Passat (B5) :: Check Engine Light After Oil Change?

My MIL light came on today for some reason. The owner's manual mentions it may be tied to an emissions problem. I just purchased this car a few months ago and had the oil changed two days ago for the first time. Could there be any connection? What are the most common reasons for the light coming on? I know with other types of cars, that light could mean one of many different things.
